安装babel-plugin-import插件。下面方法二选一，都可以实现antd的按需加载。
一、配置webpack.config.js文件
{
test: /.jsx?$/,
exclude: /(node_modules|bower_components)/,
use: [{
loader: ‘babel-loader‘
}],
options: {
"plugins": [
[
"import", {
"libraryName": "antd",
"style": true
}
]
]
}
}
二、配置babelrc文件
{
"presets": ["env", "react"],
"plugins": [
"transform-runtime",
"transform-object-rest-spread",
[
"import", {
"libraryName": "antd",
"style": true
}
]
]
}
